To ZZZ-Z whom it may concern;-

Be it known that I, XVrLL'I-AM LONG; a citizen of the United States, residing at Farina, in the county of Canyon and State of Idaho; have invented certainnew and useful In'iprov'emen ts in Fluid- Pressure Regulators, of which the following is .a specification. i

My present invention 'rei'ates to thirdpressure regulator-s, and particularly to a relief valve type of regulator adapted tor use in connection with pressure lines. or tanks, and in other like connections, to lgiiard against the pressure rising above any given oint.

An 'obi'ect is to provide it device of this character which can be connected in any pipe or hose line, or with any receptacle where fiuid is confined under PIQSSUDB, and which will automatically act to relieve the fluid pressure, should this rise above a predetermined point.

A further object is to so construct the parts that the regulator can he set to come effective at different pressures.

' Yet another object is to provide a valve structure, forming the fluid eontrolling portion of "the mechanism, which is of such character that the regulator can he used in pipe lines carrying muddy Water or other fluids or liquids which would score and inj-u re a poppet or built vsive, \vithout' heing injured or scored so that it will leaks With the above and other objects in view,

which wilt he appiii'eht to those siei'lie'din the art, my invention includes certain novel tlentin'es of construction and combinations of parts which will now he set i'crth in connection with the drawings.

In the drawing:

Figure 1 is a view in elevation of a =1"QUI-' lator constructed in accordance With my invention and with parts in hroken section, to,

A yoke B is carried on a ring?' adapted to he mounted on the base "1 -arou'nd the opening 4 and secured thereon by vmeans of cap bolts 8. At its upper end this yoke 6 has a piston chamber 9, which is preferahly provided with a cylindrical lininglfii An opening or bore 11 provided through the head portion ofthe yoke axiall -in line with the piston chamber and the circular opening 4, and supporting lugs 12 are pres viided a bo'ut midway 'onthe inner side'spf the arms of the yoke. r

A fluid pipe 13 is coh nected ivith the chamber 2 and. has its remaining end extei'idi'mg through. the H head of the yoke to open radially through the cylinder lining 10, and .a discharge pipe 14 is connected with the yoke'head and thnougl'i the eyiin: der lining 10 at a poiht substantially diametrically opposite. the opening train pipe 13. The top end of the piston chaniher "9 is closed by means of a cap le screwed on 1to 06p otherwise held in place upon: the yoke iea'. A diaphragm 16, which is of for-1n and of rut-aberor other suittib'l'e immaterial, is secured I and elaihperl between the base .1 and ring 7, and time a lases the to of fluid chamber I ph'rag'n'i is unconfined, this dia hragm is distended and raised when the pressure be- As the'i'i pper srdeo theme comes suliicieiitly great Within cha'ai'i'ber 2 to A circui ar disk or heard 17 is located on I the iipp'e'r side of the diaphragm '16 to rest at its edges on flange 5, and a steni 18cm.

roove 21 being heated at sueiifa mitten upon the length or the pist n vaive that when the is in lmverniest post-- tion, the groove is-below the openings of pipes 13 and 141, and that When the valve is raised to its uppermost position, the groove Will be in full registry with the openings of these pipes.

A ring 22 is fitted around stein 18 to bear against lugs 12, and an adjusting nut 28 is loosely fitted around stem 18 tofturn and feed within a threaded orifice inthe'ring 22. This adjusting nut 23 in turn bears. against a washer 24', and a helical spring 25 is confined between washer 24c and disk or .head'17, around the lower portion of stem K .18. This spring resiliently'u'rge s the disk U or head 17 down to a position of. rest against flange 5, in which position thevalve piston'20 isdisposed wlth'lts solid wall presented overthe'openuigs of p1 es 13 and let,

and as the pressure Within 0 amber 2 becomes sufliciently high to distend diaphragm lfland raise head 17 against the pressure of spring 25, piston valve 20 is slid up to bring groove 21 into complete or partial registry with the openings of pipes 13 and l l. This registry of the groove permits the flow oi fluid through pipe 3, chamber 2, pipe 1.3, groove 21, and discharge pipe 1 1,- back-to -the source of supply,'or' back to any suit- .mo'vement of piston valve 20 within piston chan'iber 9, and to guard against back pressure upon this valve, a bore or opening 26 is provided longitudinally through the piston -valve,slightly ofl' center to clear stem 18.

In the use of my improved regulator, piston valve 20 is normally held in the. position shown in the drawings, where the outlet end: of pipe13 opens against the solid wall of this valve,.andas the fluid is at rest within pipe 13, there is no possibilityof the valve or; cylinder 10- becoming scored or being otherwise injured. When fluid is flowing from pipe 18 to pipe14,-.gr'0ove 21 is in registry with the openings of these pipes, and dirt and gritcannot cutthe piston or cylinder. I I I q v a From the foregoing it will be seen that I have provided a fluid pressure regulator of simple construction, whichcan be installed and used. in any desired connection, and

' which'is of such construction that there is no possibility of the valve portions being; scored or otherwise injured in use.
